CAV safety benchmarking report

17 June 2021

New research published by BSI and sponsored by the UK’s Centre for Connected and Autonomous Vehicles (CCAV) contributes to global conversation on how to assess and ensure the safety of automated vehicles

BSI’s CAV Safety Benchmarking report proposes “Digital Commentary Driving” technique to be used as an objective measure of Connected and Automated Vehicles (CAV) safety performance.

The new technique involves the continuous collection of data from a CAV on its perceptions, decisions, reactions and feedback whilst driving. It is similar to “commentary driving”, a technique used to train and assess human drivers, in which they are required to verbalize relevant information in the driving scene.

RoadSafe director, Professor Nick Reed, Lead author of the report, said: “Safety is critical for the commercial deployment of connected and automated vehicles. Digital Commentary Driving is a technique by which we can analyse CAV safety performance in a standardized manner, enabling evaluation of the critical perceptions and actions that constitute automated driving behaviour.
